IP–Multimedia Subsystem (IMS) performance evaluation and benchmarking

Evaluating the IP Multimedia Subsystem (IMS) Performance is very important due to the critical role it plays in the Next Generation Network (NGN) of the Fixed and Mobile Networks. This paper proposes three robust and scalable methods that can be used to evaluate the performance, the Compliance of the IMS controllers and benchmark their different vendors. These methods are, Performance Test, FUZZING Test and the test using Spectra 2|SE tool. These issues are studied experimentally, using Open SIP Express Router (OpenSER), a high performance open source SIP server and SIPp, the de-facto standard for SIP performance benchmarking. It also provides the test results for Open SIP Express Router (OpenSER).
